I tried an experiment. After I finished processing the JPG image (Image #1 below), I opened it up again using PSE12, only I opened the JPG image in Camera RAW. Then under the Detail Tab, Noise Reduction I moved the Luminance Slider to 50. Then I clicked Open Image. Then I saved it out as a new JPG (Image #2 below). The two images below are 100% crops. You need to click on View: original size to see the difference in noise between the two images. Mind you, I am not much on post-processing and everything I do is trial and error. However, this seems to work pretty good for getting rid of noise.

Cheers.
